Light Intensity versus Distance
The relative light intensity versus distance from a point light source is plotted. As the Light Sensor is moved by hand, the string attached to the Light Sensor that passes over the Rotary Motion Sensor pulley to a hanging mass causes the pulley to rotate, measuring the position. The experiment is repeated with an extended source.
Various curves are fitted to the data to see which fits better.

Featured Equipment
Universal 550 Physics Experiment Bundle
This system provides a complete set of labs for mechanics, heat, light, sound, and electromagnetism.
550 Universal Interface
The 550 is fast, powerful, and incredibly affordable. It offers half the ports and many of the same features as our 850 Interface in a smaller package.
PASPORT High Sensitivity Light Sensor
Designed to perform visible light studies from low intensity spectral studies to daylight. Built in oversampling reduces noise. PASPORT version.
PASPORT Rotary Motion Sensor
The PASPORT Rotary Motion Sensor measures angle, angular velocity, angular acceleration and linear position, velocity, and acceleration.
Basic Optics System
A complete optics bench that includes all the components required to do introductory optics experiments.
Support
Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
